Smita Gaur has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • PIN1 peptidyl-prolyl isomerase polypeptides, their crystal structures, and use thereof for drug design
    Publication number: 20040171019
    Abstract: Polypeptides containing the PIN1 peptidyl-prolyl isomerase domain but not containing the PIN1 WW domain are described. Also described are crystal structures of these polypeptides, including the crystal structure of a PIN1 PPIase:ligand complex. The structure coordinate data derived from these crystals provides a three-dimensional description of the substrate-binding site of PIN1 peptidyl-prolyl isomerase useful in drug discovery and design for the identification and design of modulators of PIN1 peptidyl-prolyl isomerase activity.

  • Catalytic domain of the human effector cell cycle checkpoint protein kinase materials and methods for identification of inhibitors thereof
    Patent number: 6670167
    Abstract: The present invention relates to the identification, isolation and purification of the catalytic domain of the human effector checkpoint protein kinase (hChk1). A 1.7Å crystal structure of the hChk1 kinase domain in the active conformation is reported herein. The kinase domain of hChk1 and its associated crystal structure is described for use in the discovery, identification and characterization of inhibitors of hChk1. This structure provides a three-dimensional description of the binding site of the hChk1 for structure-based design of small molecule inhibitors thereof as therapeutic agents. Inhibitors of hChk1 find utility in the treatment of hyperproliferative disorders such as HIV and cancer.
